BYRON TOWNSHIP, Mich. (WOOD) — The Kent County Sheriff’s Office is investigating a tip that a bachelor party in Byron Township may be to blame for Saturday night’s big boom.

Authorities tell 24 Hour News 8 that the tipster said party members were shooting the explosive material Tannerite, which caused the noise heard dozens of miles away.

Deputies said talking with homeowners in the area 68th Street SW and Wilson Avenue in Byron Township.

However, authorities have not confirmed that the alleged Tannerite shooting was the source of the noise.

24 Hour News 8 received hundreds of reports of a loud sound about 8:30 p.m. Saturday, mostly centered around the Grandville and Wyoming areas. Kent County dispatchers said they also handled dozens of calls about the loud explosion-type sound.

Facebook exploded as well, with numerous posts to the WOOD TV8 page. “Felt like a bomb going off,” was a common comment.

Forecasters at the National Weather Service in Grand Rapids said Monday there was nothing within 100 miles weather related that would have caused the noise.

Experts at the Chaffee Planetarium in Grand Rapids also said it probably didn’t come from high up in the sky. The sound was more localized than one caused by something like a meteor, they concluded.

Anyone with information is asked to call the Kent County Sheriff’s Department at 616.632.6100 or Silent Observer at 616.774.2345.
